Surgeon Prescribing Patterns And Perioperative Risk Factors Associated With Prolonged Opioid Use After Total Shoulder Arthroplasty.

Introduction: The opioid epidemic in the United States has contributed to a notable economic burden and increased mortality. Total shoulder arthroplasty (TSA) has become more prevalent, and opioids are commonly used for postoperative pain management. Prolonged opioid use has been associated with adverse outcomes, but the role of surgeons in this context remains unclear. This study aims to investigate the incidence and risk factors of prolonged opioid utilization after primary TSA.

Methods: After obtaining institutional review board approval, a retrospective review of 4,488 primary total shoulder arthroplasties from 2014 to 2022 at a single academic institution was conducted. Patients were stratified by preoperative and postoperative opioid use, and demographic, clinical, and prescription data were collected. Prescriptions filled beyond 30 days after the index operation were considered prolonged use. Multivariate analysis was conducted to determine the independent risk factors associated with prolonged opioid utilization.

Results: Among 4,488 patients undergoing primary TSA, 22% of patients developed prolonged opioid use with 70% of prolonged users being opioid-exposed preoperatively. Independent risk factors of prolonged use include patient age younger than 65 years (Odds Ratio (OR) 1.02, P < 0.001), female sex (OR 1.41, P < 0.001), race other than Caucasian (OR 1.36, P = 0.003), undergoing reverse TSA (OR 1.28, P = 0.010), residing in an urban community (OR 1.33, P = 0.039), preoperative opioid utilization (OR 6.41, P < 0.001), preoperative benzodiazepine utilization (OR 1.93, P < 0.001), and increased postoperative day 1-30 milligram morphine equivalent (OR 1.003, P < 0.001).

Discussion: Nearly 22% of patients experienced prolonged opioid use, with preoperative opioid exposure being the most notable risk factor in addition to postoperative prescribing patterns and benzodiazepine utilization. Surgeons play a crucial role in opioid management, and understanding the risk factors can help optimize benefits while minimizing the associated risks of prolonged opioid use. Additional research is needed to establish standardized definitions and strategies for safe opioid use in orthopaedic surgery.
